You are returing a list of strings, and you try to put it in a single string.

Try this:

if(!string.IsNullOrEmpty(result))
                {
                    Coderbuddy.ExtractEmails helper = new Coderbuddy.ExtractEmails(result);
                    string[] EmailsList = helper.Extract_Emails;

                }

Damn, I overlooked at it :)

When calling a function, you'll need () at the end :)

string[] EmailsList ;

if(!string.IsNullOrEmpty(result))
                {
                    Coderbuddy.ExtractEmails helper = new Coderbuddy.ExtractEmails(result);
                    EmailsList = helper.Extract_Emails();

                }
